db1a642cd2 all: move ff_exp10, ff_exp10f, ff_fast_powf to lavu/ffmath.h
The idea is to use ffmath.h for internal implementations of math functions.
Currently, it is used for variants of libm functions, but is by no means
limited to such things.

Note that this is not exported; use lavu/mathematics for such purposes.

b2517b02d9 avfilter/af_compand: do not clip; allow >0dB curve points
Do not clip output samples, so that clipping can be handled by other filters.
Alow setting curve points above 0dB. This is useful when operating with floats.

297df52f30 avfilter/af_compand: fix clipping with default options
Decays and attacks where by default set only for first channel
which caused poor defaults to be used which produced clipping
on any higher channel.

d3cfd7aff8 af_compand: make sure request_frame always outputs at least one frame
This fixes a segmentation fault because request_frame in fifo.c assumes
that the call to ff_request_frame will populate fifo->root.next.
Before, it was possible for request_frame in af_compand to not do this,
resulting in a null pointer access. Now, request_frame in af_compand
always will return at least one frame or an error, as per the API
specifications in avfilter.h for request_frame.
